Suppose budget analysts are projecting that a particular program's costs will increase faster than overall inflation (primarily) because there will be an increase in the number of people eligible for it (e.g. Social Security and an aging population). If there is an increase in the budget by only the amount necessary to cover inflationary increases, this would be considered: multiple choice an increase if you were using baseline budgeting but a cut if you were using current-services budgeting. a cut if you were using either baseline or current-services budgeting. an increase if you were using current-services budgeting but a cut if you were using baseline budgeting. an increase if you were using either baseline or current-services budgeting.
